General Features V I R Type DSS n DS(on) 10 VIPer50A-E/ASP-E 700V 1.5A 5.7 1 TM POWERSO-10 ADJUSTABLE SWITCHING FREQUENCY UP PENTAWATT HV TO 200 kHz PENTAWATT HV (022Y) CURRENT MODE CONTROL SOFT START AND SHUTDOWN CONTROL AUTOMATIC BURST MODE OPERATION IN Description STAND-BY CONDITION ABLE TO MEET BLUE ANGEL NORM (<1w TOTAL POWER VIPer50A-E/ASP-E, made using VIPower M0 CONSUMPTION) Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an INTERNALLY TRIMMED ZENER optimized, high voltage, Vertical Power MOSFET REFERENCE (700V/ 1.5A). UNDERVOLTAGE LOCK-OUT WITH Typical applications cover offline power supplies HYSTERESIS with a secondary power capability of 25W in wide INTEGRATED START-UP SUPPLY range condition and 50W in single range or with OVER-TEMPERATURE PROTECTION doubler configuration. It is compatible from both primary or secondary regulation loop despite LOW STAND-BY CURRENT using around 50% less components when ADJUSTABLE CURRENT LIMITATION compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the ability to operate in stand-by mode Block Diagram without extra components.
